HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 423,931, dated March 25,1890.

Application filed November 15, 1888. Serial No. 290,935. (No model.) Patented in Germany March 28, 1886, No. 41,039, and May 14, 1887, No. 41,845; in Austria-HungaryApril 22, 1888,1T0.4=8,025 and No. 6.479; in England November 2, 1888,

No. 15,855, and in Belgium November 3, 1888,110. 83,824.

To all whom it may concern:

Be it known that I, JOHN KEIDEL, engineer, a subject of the King of Prussia, residing at Friedenan, near Berlin, German Empire, have invented certain new and useful 7 Improvements in HeatingSto ves, (which have been patented in the following countries: Austria-Hungary, April 22, 1888,-No. 43,025 and No. 6,479; Germany, March 28, 1886, No. 41,039, and May 14, 1887, No. 41,845 England, November 2, 1888, No.'15,855, and in Belgium November 3, 1888, No. 83,824 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Referring to the drawings, Figure 1 is a vertical axial section, taken on line A B of Fig. 3, of a magazine-stove embodying my invention. Fig. 2 is a section to right angles to that shown in Fig. 1 of the'fire-box, said section being taken in front of the grate, the adjustable front section of the fire-pot being removed. Fig. 3 is a horizontal section taken on line E F of Fig. 1. Fig. 4 is a section of the fire-box and part of the combustion-chamber, illustrating a tapering firepot; and Figs. 5 and 6 are sections similar to that shown in- Fig. 3, the former illustrating the tapering fire-pot shown in Fig. 4 and the latter illustrating an angular fire-pot.

The invention has for its object certain improvements in magazine-stoves, and more particularly in the base-section or fire-box and in the fire-pot thereof by providing means for ready removal of cinders and for the ready removal of the fire-pot itself in case such removal becomes necessary.

To these ends the invention consists in the constructionof the lower or base section of the stove and in the fire-pot, substantially as hereinafter fully described, and as specifically pointed out in the claim.

In Fig. 1, a indicates the combustion-chamber; 12, the magazine; 0, the feed-aperture, and e the smoke-flue.

That portion of the stove-body whiclrconstitutes the combustion-chamber proper has the form of a truncated cone, as shown at (Z, so as to properly direct the fuel into the firepot.- The lower portion G, or that portion which constitutes the ash-pit and contains the grate and fire-pot, has in general outline the form of a horseshoe, the quarters whereof are somewhat extended, thus forming an elongated base-section, a portion of which is semi-cylindrical or approximately so. In this base-section is formed a bearing rib or flange Z, that extends clear around the section on the inside and near its upper edge, which rib or flange forms, with the overhanging or inwardly-projecting upper edge of the base a groove m. The fire-pot g, which may be formed of grate -bars depending from the body thereof, or which may be made solid and provided with a lining of fire-brick, has substantially the form of the section Gr, and is provided along its upper edge with a flange g, that fits into the groove m, so that the fire-- pot may be slid in and out of the open end G of said base.

The open front of the fire-pot is closed by an adjustable plate or gate n, that is pivoted on lugs formed on the fire-pot, and has secured thereto an arm h, whose free end is adapted to engage a toothed rack a, formed on the under side of the roof of the extension G of the base, as shown in 1. Any other means may, however, be adopted to adjust the gate at and lock itin its adjusted position, and instead of a pivoted gate a sliding gate provided with a suitable handle 0 may be employed, as shown in Figs. 4, 5, and 6.

Instead of making the fire-pot semi-cylindrical, it may be made to taper downwardly, as shown in Figs. 4 and 5, and if the back of the base is angular in cross section instead of semi-cylindrical, as shown in Fig. 6, the firepot will have the same form.

Below the fire-pot is arranged the grate f, which may be a tilting or a shaking grate, or both.

The advantages derived from the described construction of fire-pot will be readily understood and appreciated by those conversant with this branch of the arts. In the first place it is obvious that the area of the horizontal grate may be varied within certain circuits by a proper adjustment of the gate, and thereby regulate the combustion of fuel; secondly, the swinging or sliding gate affords ready access to the grate and firepot for the removal of cinders. Finally, when it becomes necessary to renew the lining of the fire-pot, or when a new fire-pot is to be substituted for the one that'is burned out, the entire fire-pot can be moved out of the base through its open end G and lined or a new one substituted and put back.

The extended portion G of the base G of the stove is in practice closed by a suitable door providedwith the usual draftqegulating slides.

Having described my invention, what I claim is- In a stove, the combination, with the cornbustion-chamber, the base or ash-pit having an open front, and a grate arranged therein, of a fire-pot suspended within the base between the grate and combustion-chamber, said fire-pot having an open front, and an adjustable gate for said open front, substantially as and for the purpose specified.

In testimony whereof I afiix my signature in presence of two witnesses.
